How HIV infects the body

You can only catch HIV if all three of these conditions are met :

1. A body fluid with a high concentration of HIV must be present.
There are only four fluids in the human body that meet this condition:
BLOOD -- including menstrual blood
SEMEN -- including pre-cum on the tip of an erect (hard) penis
VAGINAL SECRETIONS — women slippery sexual stuff
BREAST MILK — only a concern as food for babies

2. The virus needs an entrance into someone else's body.
HIV needs to get into the bloodstream in order to infect someone. It can’t pass through healthy skin; it needs another means of entry. HIV can get inside through a break in the skin, such as a cut or a needle prick. The virus can be absorbed through a mucous membrane, the moist lining of external organs like the urethra, vagina, rectum, mouth, eye, nose. HIV can get inside much more easily through an irritation of the mucous. This includes tiny tears caused by sexual friction in either the anus/rectum or vagina, or an open sore in the mouth.

3. There must be an activity that puts one of these body fluids into contact
with one of these entry points.

The vast majority of activities can not transmit HIV. Only certain specific activities pose a risk for HIV infection, and the Risk Levels page gives you all the details.

These activities put you at the highest risk for catching HIV:

    • Vaginal or Anal Sex without a Condom and Water Based Lube
    • Sharing Penetrative Sex Toys without a Condom per person
    • Sharing Needles and other Works (for drug use, steroids, tattoos…)

You can greatly reduce your risk of contracting HIV through these activities by using water based lubricant with a latex condom and using your own new works.

Check out the Body Art and Drugs pages for more information on harm reduction, and then check out the Sex Page for more ideas, including how to play with no HIV risk at all!
